This document introduces the open source compliance guidelines of the openGemini community, aiming to help community developers and users understand and comply with the basic open source compliance guidelines and pass license compliance checks. Follow these basic guidelines when contributing to and using the community.
There are two types of open source contributor agreements: DCO.
A Developer Certificate of Origin(DCO) is developed by the Linux Foundation. The advantage of DCO is that it is relatively simple. You only need to sign your email address when submitting a PR.
Contributors are required to sign a contributor agreement when submitting a PR. Signing a contributor agreement has the following purposes:
- The copyright of the works or codes contributed to the community is granted to the project owner to facilitate the maintenance and management of the project.
- Provide the community with guarantees and disclaimers for the use of works or codes to avoid potential legal risks.
Copyright is a series of "exclusive" rights that an author enjoys legally over a certain work. It has the following characteristics:
- Enjoy it naturally without applying
- Protect expression (excluding the ideas behind it)
- Covers software, books, music, movies, etc. and other similar works
A license is a way for the owner of a copyright to grant rights to others. It can be understood as a "contract". What are the characteristics of this "contract": it does not need to be signed by both parties, and it comes into effect when the user uses the software licensed under the license.
The terms of the license consist of rights, obligations, and restrictions:
- Rights: What you can do with the software.
- Obligations: what kind of obligations you must fulfill when you use the software.
- Restrictions: what you cannot do
Common types of License include:
- Free and open source license
- Commercial license
- Other non-FOSS licenses
- Creative commons
Common licenses and their standards are listed here.
